Best Kdrama

Never regret watching this show, I've been searching for more dramas with this plot, glad that I found one. I don't want to spoil anything cos it will ruin the excitement and thrill. The actors are perfect for the role. There times that on thriller dramas/movies you'll have a hard time to grasp what's happening but here it was able to unveil the story clearly. You can feel all the emotions while watching it and also look forward for the next episode. I definitely would recommend it to everyone for them to watch.
